This was a good Sideshow Bob Episode, but I can think of much better, like Cape Feare, Brother from another series, and day of the jackanapes.
However, there were many great scenes, such as The Simpsons being impressed by the air show, Sideshow Bob getting rid of Tv, but having to send his message by TV, Homer trying to climb up the fence, the alien with the probe, and more.
So.... this was a good episode, just not up to par with other Sideshow Bob Episodes.
Overall Grade for this episode is: 85%/B+
My next review is going to be: Spongebob Squarepants: You Don't know Sponge/Hide and then what happens
